Glass substrate conveyer

A glass substrate conveyer, comprising:

• a rack, a conveying member mounted on said rack, a power system for driving said conveying member, as light sensing system mounted below said conveying member, and a controller connected with said power system, wherein
• said conveying member comprises a conveying belt mounted on said rack and a plurality of conveying rolls which are sequentially horizontally mounted on said rack, and any two adjacent conveying rolls are mutually parallel and have a gap therebetween, thereby forming a rectangular conveying member;
• said light sensing system comprises a plurality of light sensing units, the plurality of light sensing units are sequentially arranged below at least one pair of opposite sides of said conveying member and the arrangement direction thereof is parallel to the corresponding sides of said conveying member, and light rays from the light sensing units below the same pair of opposite sides are mutually parallel, for detecting glass fragments falling off a broken glass substrate;
• and
• said controller is respectively connected with individual light sensing units to receive and process signals from the light sensing units as well as send a control signal to said power system according to a processing result, and wherein
• each light sensing unit comprises two portions respectively mounted below two opposite sides of said conveying member,
• said two portions being respectively a laser distance sensor and a reflective baffle, wherein
• said laser distance sensor detects a distance from the nearest object, and
• said controller is connected with said laser distance sensor to receive a distance signal detected by said laser distance sensor and send a control signal to the power system if the received distance signal is less than a standard distance signal, said standard distance signal indicating a distance, which is detected by said laser distance sensor, from the reflective baffle.
